BACKGROUND OF THE INVENTION

Considerable effort has been directed in recent years to obtain substances useful in counteracting the consequences of hyperlipidemia, a condition involving elevated cholesterol, phospholipid and/or triglyceride levels in the blood, and of hyperlipoproteinemia, involving an imbalance of the lipo-proteins. The most serious condition associated with hyperlipidemia and hyperlipoproteinemia is atherosclerosis, a form of arteriosclerosis characterized by lipid accumulation and thickening of the walls of both medium-sized and large arteries such as the aorta. Their walls are thereby weakened and the elasticity and effective internal size of the arteries decreased. Atherosclerosis, the most common cause of coronary artery disease, is of great medical importance since it tends to occlude those arteries supplying blood to the heart muscles and brain, thereby producing permanent damage to these organs. Such damage may lead to ischemic heart disease, congestive heart failure, lifethreatening arrhythmias, senility, or stroke. Involvement of leg arteries may lead to gangrene and loss of the limb. It has been known for more than 100 years that cholesterol is a major component of atherosclerotic lesions or plaques. Investigators have been trying to determine the role of cholesterol in lesion initiation and development and also, more importantly, whether lesion formation can be prevented or reversed and enlargement of lesions be slowed or stopped. The earliest lesions are now known to be fatty streaks, largely of cholesterol, which often progress in stages to plaques containing cellular, fibrous and calcified material in addition to the lipids.

The evidence that hyperlipidemia is one of the factors involved in coronary heart disease is very impressive. A most important study carried out in Framingham, Mass. (Gordon and Verter, 1969) in over 5,000 persons for more than 12 years established a correlation between high concentrations of blood cholesterol and increased risk of heart attack. Although the causes of coronary artery disease are multiple, one of the most constant factors has been the elevated concentration of lipids in the blood plasma. A combined elevation of cholesterol and triglycerides have been shown (Carlson and Bottiger, 1972) to carry the highest risk of coronary heart disease. The majority of patients with ischemic heart disease or peripheral vascular disease were found to have hyperlipoproteinemia, involving very low-density and/or low-density lipoproteins (Lewis et al. 1974).

The reason for most treatment of hyperlipidemia or hyperlipoproteinemia is for arresting, reversing or preventing atherosclerosis. In the past, attempts have been made to lower the levels of cholesterol, phospholipids, and triglycerides in the blood by the oral feeding of various substances which have been generally referred to in the art as hypolipidemic agents or hypocholesteremic adjuvants. Typical of such substances are lecithin, pectin, cottonseed oil, and the mucilaginous substances listed in U.S. Pat. No. 3,148,114. In addition, several synthetic hypolipidemic agents are now available, namely, clofibrate, D-thyroxine, cholestyramine, and nicotinic acid [Levy and Frederickson, Postgraduate Medicine 47, 130 (1970)]. Clofibrate has the undesirable side-effect of causing hypertrophy of the liver in some patients.

The development of agents capable of reducing elevated blood lipids and of favorably altering blood-lipoprotein patterns is considered by medical authorities to be extremely important for the treatment and prevention of atherosclerosis. Related compounds are the subject of our copending U.S. Patent Application, Ser. No. 884,673.

DETAILED DESCRIPTION OF THE INVENTION

The compounds of this invention are new and novel 4-[(unsaturated or cyclopropylated alkyl)amino]phenyl compounds and derivatives of Formula I (including Formulas I-A to I-J) which have useful biological and pharmacological properties. No hypolipidemic activity has been reported in the literature for these compounds and they are different in structure from other hypolipidemic agents. The compounds of this invention lower serum-lipid concentrations and also minimize atheroma formation in the aorta. These substances also provide the oral administration required for hypolipidemic agents, which patients usually take for many years. The novel compounds of this invention are adequately absorbed from the gastrointestinal tract.

We have now found that the compounds of the present invention can safely and effectively lower both serum sterols and triglycerides in warm-blooded mammals. Such actions on serum-lipid components are considered to be very useful in the treatment of atherosclerosis, especially in contrast to available drugs whose action is much more limited. For some time it has been considered desirable to lower serum-lipid levels and to correct lipoprotein imbalance in mammals as a preventive measure against atherosclerosis. The compounds of the present invention do not act by blocking late stages of cholesterol biosynthesis and thus do not produce accumulation of intermediates such as desmosterol, as equally undesirable as cholesterol itself. Compounds with the combination of therapeutically favorable characteristics possessed by those of the present invention can be safely administered to warm-blooded mammals for the treatment of hyperlipidemic and atherosclerotic states found in patients with or prone to heart attacks, to peripheral or cerebral vascular disease, and to stroke.

The novel compounds of the present invention are, in general, white crystalline solids having characteristic melting points and absorption spectra. They are soluble in organic solvents such as lower alkanol, chloroform, benzene, dimethylformamide, and the like, but are generally not very soluble in water. The novel compounds of the present invention, which are organic bases may be converted to their non-toxic acid-addition or cationic salts with a variety of pharmaceutically acceptable organic and inorganic salt-forming reagents. Thus, acid-addition salts may be formed by admixture of the organic free base in a neutral solvent with one or two equivalents of an acid such as sulfuric, phosphoric, hydrochloric, hydrobromic, trifluoroacetic, citric, ascorbic, and the like. The compounds which contain acidic groups form pharmaceutically acceptable cationic salts with organic or inorganic bases such as the alkali metal hydroxides, the alkaline earth metal hydroxides, and the like. The sodium or potassium salts which are formed in solution in the course of hydrolysis of their esters can be isolated as the solid alkali metal salts by cooling. Where it is desirable to purify a compound in the form of the acid, the salt is conveniently formed by treating its solution with exactly one equivalent of base and evaporation or lyophilization. Alkaline earth salts are prepared similarly, often using their acetate salts as a conveniently soluble form. Organic base salts such as those of N-methylglucamine are prepared by dissolving equimolar amounts of the acid and the base in hot ethanol or aqueous alcohols and cooling to crystallization.

The 4-[(unsaturated or cyclopropylated alkyl)amino]phenyl compounds of this invention are prepared by reaction of the corresponding 4-aminophenyl compounds with suitable alkylating agents, such as (unsaturated or cyclopropylated alkyl) halides, sulfates, tosylates, mesylates or trifluoromethylsulfonates, with or without a solvent at 25°-150° C. Suitable solvents are lower alkanols, chloroform, N,N-dimethylformamide, N,N-dimethylacetamide, diglyme, dimethylsulfoxide, acetonitrile, toluene, benzene, hexamethylphosphoramide and like solvents. The reaction may be carried out with 2 equivalents of the unsubstituted amine compound or with only one equivalent and one equivalent of an unreactive organic base such as diisopropylethylamine or an alkali carbonate or bicarbonate, or with a catalytic amount of copper powder when an appropriate halide is used as the alkylating agent.

The N-acetyl-4-(substituted-amino)phenyl compounds are prepared by reaction of a corresponding 4-(acetylamino)phenyl compound with an appropriate (unsaturated or cyclopropylated alkyl) halide in the presence of an equivalent of sodium hydride in an inert solvent such as N,N-dimethylformamide, N,N-dimethylacetamide or diglyme at 50°-150° C. The N-acetyl compounds are readily hydrolyzed to the acids in boiling aqueous ethanolic dilute alkali or acid.

Alternative methods of preparation are by reductive alkylation of a 4-aminophenyl compound which may also be generated in situ by reduction of 4-amino precursors such as a 4-nitro group and the like, or by a borohydride reduction of a 4-(acylamino)phenyl compound. For example, a carbonylalkene such as an unsaturated ketone or aldehyde and ethyl 4-aminophenylacetate and the like are reduced under 1-10 atmospheres of hydrogen using a suitable metal catalyst or with a metal hydride such as sodium borohydride forming the corresponding phenylacetic acid and the like. Diborane reduction of 4-(cyclopropylalkanoylamino)phenyl compounds such as ethyl 4-(11-cyclohexylundecanoylamino)phenylacetate at room temperature or above for 1-6 hours yields the corresponding 4-(cyclopropylalkylamino)phenyl compounds such as ethyl 4-(11-cyclopropylundecylamino)phenylacetate. The 4-(cyclopropylalkanoylamino)phenyl compounds used in these reductions are prepared by acylation of the appropriate 4-aminophenyl compounds with suitable acylating agents, such as cyclopropylalkanoyl halides. To prepare the 4-(substituted-amino)phenyl alkenoic and alkynoic acids it is advantageous to form the corresponding alkylchloromide from the 4-(acylamino)phenyl compounds using phosphorous oxychloride and base, and then reduce the alkylchloromide moiety to an alkylamino group with sodium borohydride.

The 4-(substituted amino)phenyl compounds of this invention are often prepared from the corresponding p-aminophenyl compounds by the sequence involving esterification of any carboxyl group present with ethanol or methanol in the presence of boron trifluoride etherate, followed by alkylation of the amino function as described above. The free acids are then liberated by hydrolysis of the ester with aqueous alcoholic sodium hydroxide at 80° C. for 2-10 hours followed by acidification. The acids obtained by this procedure may be converted to the corresponding cationic salts. For example, the sodium salt may be prepared by reaction of the benzoic acid with sodium hydroxide in a mixture of ethanol and water. Alternatively, the free acids may be prepared by hydrolysis of the corresponding nitriles or various amides, imidates or oxazolines.

The 4-[(unsaturated or cyclopropylated alkyl)amino]phenyl compounds and derivatives are prepared by deacylation of the corresponding 4-[(N-trifluoroacetyl)-(unsaturated or cyclopropylated alkyl)amino]phenyl compounds by reacting with an alkali hydroxide such as sodium or potassium hydroxide in a lower alkanol, water or an aqueous lower alkanol at 5° C. to 50° C. Alternatively, these compounds may be prepared by deacylation of the 4-(N-carbo-t-butoxyalkenylamino) phenyl compounds with mineral acids such as hydrochloric or hydrobromic acid, preferably in glacial acetic acid at 0° C. to 50° C. Also, they are prepared by removal of the carbobenzyloxy protecting group from the anilino nitrogen atom by means of mild catalytic hydrogenation or by treatment with a mineral acid such as hydrobromic acid in glacial acetic acid.

A method useful for the introduction of the (unsaturated or cyclopropylatedalkyl)amino group into aromatic compounds is nucleophilic aromatic substitution. An example of this method is the reaction of 2-(cyclopropyl)ethylamine (or the anion derived therefrom by treatment with a strong base) with ethyl 4-fluorobenzoate to yield ethyl 4-[2-(cyclopropyl)ethylamino]benzoate. In certain instances an amine such as 2-(cyclopropyl)ethylamine may be reacted with a benzyne such as that derived from ethyl 4-bromobenzoate by treatment with sodium amide to yield the 4-(substituted amino)phenyl compound, in this case ethyl 4-[2-(cyclopropyl)ethylamino]benzoate.

Certain derivatives ##STR6## of the aminobenzoyl nitrogen atom are useful for providing greater solubility, more uniform and reliable intestinal absorption, and for a certain degree of modification of the pharmacology of the compounds of the present invention. Some of these derivatives can be converted to the corresponding N--H forms by the acidity of the stomach or the alkalinity of the small intestine. Others are converted by metabolic processes. The methyl and carboxymethyl derivatives and the like are prepared by the alkylation, reductive alkylation, and acylamino reduction methods above. Derivatives such as the acetyl and succinyl compounds may be prepared using acetyl chloride, acetic anhydride, succinic anhydride, etc., in the presence of pyridine, triethylamine or the like at temperatures moderate enough to avoid acylation of the amide moiety. The 1-(sodium sulfo)alkyl derivatives are obtained by reaction of the 4-[(unsaturated or cyclopropylated alkyl)amino]phenyl compound with sodium bisulfite and an aliphatic aldehyde, a polyhydroxyaldehyde such as glyceraldehyde or glucose, or cinnamaldehyde in a mixed organicaqueous medium. In the case of cinnamaldehyde, the di-sulfonate salts result from addition of the bisulfite to the carbon-nitrogen double bond of the anil intermediate as well as to the carbon-carbon double bond of cinnamaldehyde itself.

In certain cases, the unsaturation is introduced at a late stage of the preparation, of the 4-(unsaturated alkylamino)phenyl compounds. For example, a 4-(ω-haloalkylamino)phenyl compound is dehydrohalogenated to the corresponding olefinic compound or, alternatively, it is converted to a Wittig trialkylphosphonium reagent and reacted with an aldehyde to yield a product with an internal double bond. This ω-halo substrate can also be reacted with an alkylacetylene sodium or lithium salt to form the corresponding 4-alkynylamino derivatives.

The carboxaldehydes of this invention may be prepared by several methods among which is alkylation of the corresponding acetals as described above followed by hydrolysis of the resulting 4-(substituted-amino)phenyl compound to the desired aldehyde. Aldehydes may also be prepared by reduction of the appropriate nitriles. For example, treatment of 4-(hex-3-enylamino)hydrocinnamonitrile with stannic chloride and anhydrous hydrogen chloride gas, followed by hydrolysis in hot water provides 4-(hex-3-enylamino)hydrocinnamaldehyde. These reductions are also conveniently carried out with hydrides such as diisobutylaluminum hydride.

The α-substituted 4-(substituted-amino)acetophenones of the invention are prepared by reaction of a derivative of the appropriate benzoic acid, such as 4-(4-pentadecenylamino)phenylacetyl chloride hydrochloride, with two or more equivalents of the reactive salt of an acidic methylene compound, for example the sodium salt of diethyl malonate. Other benzoic acid derivatives are also suitable for this reaction, such as an N-trifluoroacetyl or N-tertbutyl-oxycarbonyl acid chloride, or a methyl ester of the acid. In some cases the final step in the preparation of the α-substituted 4-(substituted-amino)acetophenone is the removal of the nitrogen-protecting group. In other cases, hydrolysis of one or more of the ester groups in the acylation product affords an unstable polycarboxylic acid which undergoes decarboxylation to allow the preparation of another acetophenone derivative. For example, the reaction of tert-butyl ethyl [4-(4-pentadecenylamino)benzoyl]malonate with trifluoracetic acid affords ethyl [4-(4-pentadecenylamino)benzoyl]acetate. In other cases, hydrolysis of one or more of the ester groups allows the preparation of the corresponding acid derivative. For example, the hydrolysis of ethyl [4-(hept-3-enylamino)benzoyl]acetate yields 4-(hept-3-enylamino)benzoylacetic acid.

An alternative procedure for preparing certain 4-(substituted-amino)acetophenones is alkylation of the corresponding 4-aminoacetophenone by the methods above. For example, alkylation of methyl 3-(4-aminobenzoyl)propionate with undec-10-enyl bromide yields methyl 3-[4-(undec-10-enylamino)benzyl]propionate. The related carboxylic acids are then obtained by hydrolysis. Certain of these acids are particularly useful for the preparation of 4-(substituted-amino)phenylalkanoic acids by reduction. For example, the Clemmensen or Wolff-Kishner reduction of 3-[4-(hex-3-enylamino)benzoyl]propionic acid yields 4-[4-(hex-3-enylamino)phenyl]butyric acid.

The 4-(substituted-amino)phenylalkenoic acids may be prepared by condensation of the appropriate aldehydes or by dehydration of the corresponding substituted phenylhydroxyalkanoic acids. For example, ethyl 5-[4-(undec-10-enylamino)phenyl]-2,4-pentadienoate is obtained by the Wittig reaction of 4-(undec-10-enylamino)benzaldehyde with the Wittig reagent, triethyl 4-phosphonocrotonate. Alternatively, these alkenoic acids are obtained by heating 4-[N,N-disubstituted-amino]benzaldehyde and the like with the sodium salt of the carbanion of ethyl acetate or with a mixture of ethyl acetate, acetic anhydride and potassium acetate. The second method is illustrated by dehydration of ethyl 3-[4-(undec-10-enylamino)phenyl]-3-hydroxypropionate to the corresponding cinnamate.

The acetylenic analogs are prepared by dehydrobromination of the side-chain vic-dibrominated alkanoic acid. For example, dehydrobromination of ethyl 3-[4-(allylamino)phenyl]-2,3-dibromopropionate, its isomers or N-acyl analogs or of ethyl 3-[4-(allylamino)phenyl]-3-bromoacrylate yields ethyl 4-(allylamino)phenylpropiolate. The acetylenic acids are also formed from (4-substituted-amino)pehnylacetylene metal salts by carboxylation with carbon dioxide. The 4-(substituted-amino)phenylacetylenes are also prepared by N-acylating with t-butyl azidoformate followed by conversion to the lithium acetylide salt and the subsequent reaction of the lithium salt with boron trifluoride etherate in tetrahydrofuran at -20° C. to form tris-[(4-substituted-amino)phenylethynyl]boranes. The tetrahydrofuran solution of the borane is in turn reacted with ethyl diazoacetate, followed by water to yield ethyl 4-[(4-substituted-amino)phenyl]butynoate

The 4-(substituted-amino)phenylalkanoic acids, or esters are also prepared by catalytic reduction at 1 to 10 atmospheres of hydrogen of the corresponding alkenoic or alkynoic acid derivatives.

The 4-(substituted-amino)phenylalkenoic acids and derivatives are prepared by Friedel-Crafts acylation of the N-acyl-N-alkylanilines with the appropriate dicarboxylic acid anhydride or half acid chloride. The 4-(substituted-amino)benzoylalkanoic acids or esters, obtained by this and by other syntheses, may be converted to the corresponding 4-(substituted-amino)phenylalkanoic acids by reduction with (a) hydrazine and alkali in diethylene glycol at 140° for 3 hours, (b) zinc amalgam and ethanolic hydrochloric acid at 60° for 5 hours, (c) red phosphorus and hydriodic acid, or (d) ketalization with 1,2-ethanedithiol followed by Raney nickel desulfurization. The amides of these 4-(substituted-amino)phenylalkanoic acids are prepared by heating the corresponding 4-(substituted-amino)phenylalkyl ketones with aqueous alcoholic ammonium polysulfide followed by hydrolysis to yield the acids with the same number of carbon atoms as the ketone. These acids are also prepared by reacting 4-(N-t-butyloxycarbonyl-N-substituted-amino)phenylmagnesium halides with 2-(3-halopropyl)-2-oxazolines, followed by mild acid removal of 2-oxazolinyl and t-butoxycarbonyl protecting groups. Similarly, the above Grignard reagent can be reacted with 3-bromotriethylorthopropionate in the presence of dilithium-tetrachlorocuprate to yield the desired acids after removal of the protecting groups from the amino and carboxyl groups.

The novel 4-(substituted-amino)phenyl compounds of the present invention are not only potent hypolipidemic agents but also prevent or diminish the formation or enlargement of arterial plaques in mammals when administered in amounts ranging from about one mg. to about 250 mg. per kilogram of body weight per day. A preferred dosage regimen for optimum results would be from about 5 mg. to about 100 mg. per kilogram of body weight per day, and such dosage units are employed that a total of from about 0.35 grams to about 7.0 grams of the active compound, for a subject of about 70 kg. of body weight, are administered in a 24 hour period. This dosage regimen may be adjusted to provide the optimum therapeutic response. For example, several divided doses may be administered daily or the dose may be proportionally reduced as indicated by the exigencies of the therapeutic situation. A decided practical advantage of this invention is that the active compound may be administered in a convenient manner by the oral route. The compounds of the present invention exert a more powerful hypocholesteremic and antiatherosclerotic effect than the aforementioned adjuvants and synthetic medicaments. It is not known how these novel compounds operate in the blood serum and no theory of why these compounds so operate is advanced. It is not intended that the present invention should be limited to any particular mechanism of action of lowering serum lipids or of ameliorating antherosclerosis, or be limited to compounds acting by only one mechanism.

The active compounds of the present invention may be orally administered, for example, with an inert diluent or with an assimilable edible carrier, or they may be enclosed in hard or soft shell gelatin capsules, or they may be compressed into tablets, or they may be incorporated directly with the food of the diet. For oral therapeutic administration, the active compounds may be incorporated with excipients and used in the form of ingestible tablets, buccal tablets, troches, capsules, elixirs, suspensions, syrups, wafers, and the like. Such compositions and preparations should contain at least 0.1% of active compound. The percentage of the compositions and preparations may, of course, be varied and may conveniently be between about 2 to about 60% of the weight of the unit. The amount of active ingredient in such therapeutically useful compositions is such that a suitable dosage will be obtained. Preferred compositions or preparations according to the present invention are prepared so that an oral dosage-unit form contains between about 50 and 250 milligrams of active compound.

The tablets, troches, pills, capsules and the like may also contain the following: a binder such as gum tragacanth, acacia, corn starch or gelatin; excipients such as dicalcium phosphate, a disintegrating agent such as corn starch, potato starch, alginic acid and the like; a lubricant such as magnesium stearate; and a sweetening agent such as sucrose, lactose or saccharin may be added or a flavoring agent such as peppermint, oil of wintergreen, or cherry flavoring. When the dosage-unit form is a capsule, it may contain, in addition to materials of the above type, a liquid carrier. Various other materials may be present as coatings or to otherwise modify the physical form of the dosage unit. For instance, tablets, pills or capsules may be coated with shellac, sugar or both. A syrup or elixir may contain the active compound, sucrose as a sweetening agent, methyl and propyl parabens as preservatives, a dye, and flavoring such as cherry or orange flavor. Of course, any material used in preparing any dosage-unit form should be pharmaceutically pure and substantially non-toxic in the amounts employed. In addition, the active ingredients may be incorporated into sustained-release preparations and formulations.

The invention will be described in greater detail in conjunction with the following specific Examples.

EXAMPLE 1 Preparation of p-(allylamino)phenylacetic acid; (Method A)

To a solution of 18.2 g. of ethyl p-aminophenylacetate in 100 ml. of dimethylformamide is added a solution of 4.7 ml. of allyl bromide in 60 ml. of dimethylformamide. The solution is heated at 60° C. for 5 hours and then cooled and partitioned between diethyl ether and water. The combined ether phases are washed with water, dried over magnesium sulfate, and concentrated in vacuo to provide 16.5 g. of a semi-solid. A portion (6 g.) is absorbed onto 30 g. of silica gel and chromatographed on 475 g. of silica gel to provide ester.

A mixture of the ester 22.0 g. of potassium hydroxide and 200 ml. of ethanol-water (8:1) is stirred under reflux for 6 hours. Concentrated hydrochloric acid (about 80 ml.) is added to the warm mixture and cooling and dilution with water affords a white solid which is collected by filtration and recrystallized from ethanol to yield the product as a white solid.

The reaction mixture is stirred at -10° C. for 30 minutes and then diluted with methylene chloride, extracted with ice-water (250 ml.); followed by cold 10% hydrochloric acid (200 m.); cold saturated sodium bicarbonate (200 ml.) and cold brine (200 ml.). The organic phase is dried over magnesium sulfate and the solvent removed in vacuo to provide the crude mesylate.

A solution of 18.1 g. of the above mesylate and 19.8 g. of ethyl p-aminophenylacetate in hexamethylphosphoramide is heated at 120° C. for 20 hours. After cooling, the reaction mixture is diluted with 30 ml. of ethanol:water (1:1) (30 ml.) and chilled. More ethanol is added and the solid material is collected. This solid is recrystallized twice from ethanol to provide the ester.

EXAMPLE 319 Preparation of p-[1-(2,3-methano)octylamino]phenylacetic acid

To a stirred mixture of 5 g. of zinc-copper couple prepared by the Shank-Shechter Method [R. S. Shank and H. Schehter, J. Org. Chem., 24, 1825 (1959)], 0.02 g. of iodine, and 100 ml. of anhydrous ether is added 8.7 g. of (0.05 mol) of methylene iodide. The mixture is heated in the absence of atmospheric moisture until a spontaneous reaction begins as evidenced by continued refluxing of the ether when the heat source is removed. Upon completion of the exothermic reaction, the mixture is refluxed for 30 minutes, the heat is removed and to this mixture is added a solution of 5.4 g. (0.04 mol) of cis-2-octenol [L. P. Paquette and R. F. Eizember, J. Am. Chem. Soc., 91, 7110 (1969)] in 10 ml. of anhydrous ether at a rate sufficient to maintain constant reflux. When the addition is complete, the mixture is refluxed for 3 hours. The flask is cooled and the mixture is filtered and the filtrate is washed with cold dilute hydrochloric acid and saturated sodium bicarbonate, dried and evaporated to give Z-1-hydroxymethyl-2-n-pentylcyclopropane.

Preparation of the tosylate by the method of Example 2, followed by condensation with ethyl-p-aminophenylacetate by the method of Example 2, followed by saponification by the method of Example 2 provides p-[1-(2,3-methano)octylamino]phenylacetic acid.

EXAMPLE 320

Treatment of the indicated olefin of the Table II with Zinc and diiodomethane by the method of Example 319 to produce the corresponding cyclopropyl compound followed by treatment of the halide with ethyl p-aminophenylacetate by the method of Example 1, followed by saponification of the resulting ester by the method of Example 1, is productive of the p-(methanoalkyl)aminophenylacetic acid of Table II (Method C).

Treatment of the olefinic alcohols of Table II with Zinc and diodomethane by the method of Example 319 will produce the corresponding cyclopropyl alkanols which upon treatment with methanesulfonic anhydride (Method of Example 2) will produce the corresponding methanesulfonate ester which upon treatment with ethyl p-aminophenylacetate by the procedure of Example 2 followed by saponification will produce the p-(methanoalkyl)aminophenylacetic acids of Table II (Method D).

To a cold (-20°) stirred solution of 10.8 g. 1-hydroxypentadec-4-ene prepared by lithium aluminum hydride reduction of methyl tetradec-3-encarboxylate and 13.4 ml. triethylamine in 300 ml. ether is added dropwise 5.6 ml. methanesulfonyl chloride in 5 ml. of either. After addition is completed, the solution is warmed to room temperature, stirred for 30 minutes and filtered directly into a solution of 23.1 g. ethyl 4-aminophenyl acetate in 100 ml. ether. After 17 hours at room temperature, the precipitate is filtered and washed with several portions of methylene chloride. The organic solution is washed twice with 100 ml. water, 100 ml. brine, dried and evaporated. The tan residue is crystallized from ethanol and from acetonitrile to yield the title compound as white crystals.

EXAMPLE 365 Preparation of ethyl 4-(1-pentadeca-4,14-dienylamino)hydrocinnamate

A solution of 8.6 ethyl 4-aminohydrocinnamate, 9.77 g. 3,13-tetradecadien-1-carboxaldehyde and a few crystals of 2,4-dinitrobenzenesulfonic acid in 250 ml. toluene is refluxed under a Dean-Stark trap for 17 hours, whereupon the theoretical amount (0.8 ml.) water has been collected. The toluene is evaporated to yield ethyl 3-[4-(1-pentadeca-4,14-dienylideneaminophenyl]propionate as a crystalline mass.

To a mixture of 17.8 g. of the above compound in 250 ml. ethanol is added 1.68 g. sodium borohydride and the mixture is stirred at room temperature for 18 hours. Excess reagent is decomposed by addition of 10 ml. acetic acid. The solution is concentrated in vacuo and the residue is partitioned between toluene and aqueous potassium carbonate. After drying, the toluene is evaporated to yield a solid. Crystallization from acetonitrile and from ethanol affords the title compound as white crystals.
